MARK IV / GOUND SWITCH?

[jcalabro]

Hi i just had a quick question. i just recieved my Mark IV that i purchased, and when looking at the back i see a "ground" switch with A - OFF - B.
The manual has nothing about this ground switch in it or on it.
Can anyone help me with this on? Where should it be placed? Thanks alot!

I don't own it, but i've read the manual. One way grounds to the chassie (sp?) and the other grounds to the mains (third prong on the plug-in).

It doesn't matter which way you ground it. Just look for the least hum. You will really know when your lip touches a live mic. If you get a tingle, you are probably ok, but it will bite if you need to switch it.

Hope this helps.
